fix(normalization): Phase 143 execution fix - Param region SSOT
Problem: normalized_helpers allocated env params as ValueId(1,2...)
in PHI Reserved region (0-99) instead of Param region (100-999)
per JoinValueSpace contract.
Root cause: All 4 normalized shadow modules started from
next_value_id=1, violating the Param region contract.
Solution:
- Add NormalizedHelperBox::alloc_env_params_param_region()
that allocates params starting from PARAM_MIN (100)
- Update 4 normalized shadow files to use new API:
- loop_true_if_break_continue.rs
- loop_true_break_once.rs
- if_as_last_join_k.rs
- post_if_post_k.rs
- Fix instruction_rewriter.rs type mismatch
(func.signature.params → func.params)
Verification:
- Unit tests: 69/69 PASS
- VM smoke: exit code 7 ✅
- LLVM EXE smoke: exit code 7 ✅ (timeout resolved!)
ValueId Space Contract (Phase 201):
| Region | Range | Purpose |
|--------------|----------|------------------------------|
| PHI Reserved | 0-99 | Loop header PHI dst |
| Param | 100-999 | env params (flag, counter) |
| Local | 1000+ | Const, BinOp, condition |
